American rapper Ludacris says he has "a huge crush" on supermodel Heidi Klum, the host of Sunday's MTV European music awards show.

Ludacris, alt-pop trio Fun and Canadian singer-songwriter Carly Rae Jepsen took a rehearsal break to attend a press briefing Saturday ahead of the MTV EMA in Frankfurt. Joined by Klum, all talk turned to the upcoming festivities.

Ludacris said he felt "blessed" to be in Frankfurt and saw the awards as a chance to "give back to the global fans" — and also get near Klum. The rapper will exclusively premiere his new music video "Rest of My Life," featuring Usher and David Guetta, during the show.

Also taking the stage will be Jepsen, who soared to the top of the charts with hit song "Call Me Maybe" and has three nominations. She said she is already "falling a little bit in love with Frankfurt."

Others performing will include Taylor Swift, Muse, No Doubt, Alicia Keys, Pitbull, Psy and The Killers. Also in the line-up is Fun, who said they would get "pretty giddy" if they bumped into The Killers backstage because they are huge fans.

Klum, meanwhile, was excited to cross paths with Psy, the South Korean phenomenon, and admitted she and her children are partial to his "Gangnam Style" dancing.

The 19th annual MTV EMA will broadcast live Sunday from Frankfurt's historic Festhalle.
